An extraordinary discovery in 21st century science has been made if confirmed: evidence of something that occurred before the Big Bang. Our cosmos was “bruised” in collisions with other universes. Astronomers, led by Sir Roger Penrose, mathematical physicist and Emeritus Rouse Ball Professor of Mathematics at the Mathematical Institute, University of Oxford and Vahe Gurzadyan at Yerevan State University in Armenia have found the first evidence of these impacts in the cosmic microwave background data acquired by the Planck Space Observatory designed to observe the anisotropies of the cosmic microwave background (CMB), using high sensitivity and angular resolution.
Last month the duo announced that they had found patterns of concentric circles in the cosmic microwave background, the echo of the Big Bang, which what you’d find if the universe were eternally cyclical. By that, they mean that each cycle ends with a big bang that starts the next cycle. In this model, according to MIT’s Technology Review, “the universe is a kind of cosmic Russian Doll, with all previous universes contained within the current one.”
When cosmologist get to analyze the new data, these circles “should either spring into clear view or disappear into noise (rather like the mysterious Mars face that appeared in pictures of the red planet taken by Viking 1 and then disappeared in the higher resolution shots from the Mars Global Surveyor)” according to Technology Review.
